Admission requirements for engineering grad programs

I am hoping someone can provide me with some information about what undergraduate courses are typically expected on an applicants transcript for engineering masters programs. I presume the different disciplines of engineering require different classes as prerequisites, so I'd be interested in hearing about them all, if possible.

I have an undergraduate degree in economics and currently work full-time. I made a decision late in undergrad that I wanted to attend grad school for economics, which typically requires Calculus 1-3, Differential Equations, and Linear Algebra as minimum requirements. These are not classes I ever considered taking until I realized they'd be necessary for something I wanted to achieve, so I decided that it'd be best for me to finish my degree and take these classes while working. So far I have stuck to my plan and am currently enrolled in Calc 2 and find the subject very interesting. I seem to enjoy the engineering applications as much as topics I studied in economics and the type of work engineers do appeals to me. I have just begun to scratch the surface of considering a new path, so I wanted to see what requirements I would be faced with to even enroll in engineering grad programs. Thanks for the help!

If you have a specific university in mind, then the web sites for its engineering department(s) should give you a good idea what is needed.

The math courses you listed are probably adequate preparation for most master's programs. But just as important will be some undergraduate engineering courses in whatever degree you're pursuing. E.g., if you want a MSEE you'll probably have to bring at least some of the following to the table, depending on what field within EE: signals and systems, probability and random processes, circuit analysis, electromagnetism, communication theory, digital logic/design, etc., etc.

And you will probably need some kind of proficiency with computer programming if you don't already have it. I don't know what language is the standard at universities these days; it was C when I was in school but that was ~20 years ago.
